Hi Nirish

I struggled for 2 years with frequent calf muscle spasms, cramps, strains, tears, etc. As everyone is different, just a few things to checklist:
Technique, has it changed recently ?
Are you a heel, mid or forefoot runner ?
Change of running shoes ?
Old injuries ?
Anything else health wise that could cause muscle issues ?
Sitting longer at work or play ?

I live and travel with a foam roller. I use it carefully to daily work the calf and hamstrings. It has helped me to get beyond that threshold so I can now run without significant calf issues. It took 2 years of therapy, technique change & persistance !
Look on youtube for some careful foam roller use for your situation, dont just knead away without knowing the guidelines.
Hope you can get on top of the issue !
